Ma motors opanda maburashi ndiabwino kwambiri, chifukwa chiyani pali ntchito zambiri zama motors opanda brush?

M'moyo watsiku ndi tsiku, zida zonse zazing'ono zam'nyumba ndi zida zamagetsi ziyenera kuyendetsedwa ndi ma micro-motor DC motors.Anthu osamala apeza kuti kuwonjezera pa ma mota a AC, enawo ndi ma motor-DC, ndipo zinthu zambiri zimagwiritsa ntchito ma mota a DC.Ma motors a Brushless Micro DC, monga makina a khofi, malezala, zotsukira kumaso, zida zokongola, ndi zina zambiri, sagwiritsidwa ntchito kawirikawiri mu ma brushless micro motors.Chifukwa chiyani?

Tikudziwa kuti motor brushless ili ndi liwiro lalitali, phokoso lotsika komanso moyo wautali wautumiki, pomwe mota ya brushless ndiyotsika pang'ono.Koma brushed yaying'ono DC motor imatha kuthamanga bola italumikizidwa ndi mphamvu ya DC, ndipo kuwongolera ndikosavuta.Itha kuwongoleredwa powonjezera kapena kuchepetsa mphamvu yamagetsi.Galimoto ya brushless micro-DC imafunika mabwalo owonjezera kuti agwire ntchito, ndipo torque ndi yaying'ono ikathamanga kwambiri.Ngati torque ikufunika, chochepetsera chiyenera kuwonjezeredwa, chomwe chimafuna njira zopangira zinthu zambiri komanso mtengo wake.

Brushless micro DC motorsnthawi zambiri amafunikira masensa atatu a Hall kuti agwire ntchito, chifukwa mapindikidwe atatu a injini yaying'ono ndi 120 °.Kuti muyese malo atatu a rotor yofananira, masensa atatu a Hall amafunikira.Amakhalanso ogwirizana Amagawidwa pa 120 °, mu wiring, Nyumba yobwereranso iyenera kukhazikitsidwa pakati pa Nyumba ziwiri, zomwe zingathe kufupikitsa waya wotsogolera.Muyenera kudziwa kuti brushless DC motor ilibe chipangizo cha burashi.Burashi ndi commutator zimasinthidwa ndi masensa a Hall.Chifukwa chake, idzakhala ndi mphamvu zambiri, phokoso lochepa, kudalirika kwakukulu, kuwongolera pafupipafupi kutembenuka kwachangu komanso moyo wautali wautumiki.Mawonekedwe a Ultra-high liwiro.

Mwachidule, kuti aDC moterekuti agwire ntchito, nthawi zonse payenera kukhala mbali ina pakati pa mphamvu ya maginito ya koyilo ya stator ndi maginito a maginito okhazikika a rotor.Njira yozungulira ya rotor (ndiko kuti, njira yosinthira njira ya maginito) ndikupangitsa kuti maginito awiri akhale ndi ngodya.Pambuyo pa digiri inayake, mayendedwe a maginito a stator coil ayenera kusinthidwa, ndipo Nyumba zitatuzi zingagwiritsidwe ntchito kudziwa njira yosinthira mphamvu ya maginito ya stator.Mwa kuyankhula kwina, Nyumba zitatuzi ndi ntchito youza wolamulira nthawi yoti asinthe panopa.

Chifukwa chake, zinthu zambiri zamagetsi zimagwiritsa ntchito ma brushed micro DC motors kwambiri.Njira yoyambira yoyendetsera ma brushless DC motors ndizovuta kwambiri.Pokhapokha ngati ndi chinthu chomwe chili ndi zofunikira kwambiri, ndipo ma brushed micro motors sangathe kuzindikirika, adzagwiritsidwa ntchito.Brushless DC mota.
